Answer:

13.5ms

Step-by-step explanation:

Here

u =3ms

a=1.5m/s2

t=7s

Using

v= u + at

v=3ms+(1.5m/s2 × 7s)

v = 3ms+ 10.5ms

v= 13.5ms

9. Simplify the expression. 4x + 7y - 2 + 6y + 6y - 8x - 5 Your answer
morpeh [17]

Answer:

9. -4x+19y-7

10. 7x+20

Step-by-step explanation:

9. To simplify this expression, simply combine like terms. Add all of the terms with the x variable together, then the terms with the y variable, then the constant terms. I will show this step by step, but usually you do not have to show this work. The order of the terms does not matter.

x variable terms: (4x-8x)+7y-2+6y+6y-5= -4x+7y-2+6y+6y-5

y variable terms: (7y+6y+6y)-4x-2-5=19y-4x-2-5

constant terms: (-2-5)-4x+19y=-4x+19y-7

10. To simplify this expression, expand all terms and then combine like terms. The first term can be expanded by multiplying each term in the parentheses by 2.

Expand terms: 2(5+3x)+(x+10)= 10+6x+x+10

Now, you can combine like terms as done on the last problem. Note that I got rid of the parentheses in the second term, as they did not matter (since there was no term in front of them).

x variable terms: (6x+x)+10+10=7x+10+10

constant terms: (10+10)+7x=7x+20

A room is 20 feet long.If a couch that is 12 1/3 feet long is to be centered in the room how big of a table can be placed on wit
olchik [2.2K]
20-12 1/3=7 2/3 or 23/3.   so there is a total of 23/3 ft available.  We then take half of that for each side.  1/2 of 23/3= 1/2*23/3= 23/6

22,403 Check:<br>- 8,675<br><br>how i do this​
vodomira [7]

Answer:

Hello!! :) The answer to your question is 13,728

Steps will be below.

Step-by-step explanation:

So we will subtract 22,403 and 8,675.

When we do that we will get 13,728

To check your answer we have to do the opposite of subtracting which will be adding.

This is how we check our work: the answer we got was 13,728...we have to take that answer and add it to 8,675 which will give us 22,403

(Both of the numbers are from the question)

At the bottom I attached a picture of how I did the subtracting and how I checked my work.

Sorry for my handwriting......if you can’t understand my handwriting, I attached another picture which is more clearer.

ANSWER TO YOUR QUESTION: 13,728

Brainliest would be appreciated! Thank you :3

Hope this helps! :)

What transformation has changed the parent function f(x) = log3x to its new appearance shown in the graph below?
Wittaler [7]

Answer : option B

Parent Graph f(x) = log_3(x) is attached below

We analyze each option

A) f(x − 2) --> x - 2 shifts the graph 2 units to the right

B) f(x + 2) --> x + 2 shifts the graph 2 units to the left

C) f(x) − 2 --> f(x) - 2 shifts the graph 2 units down

D) f(x) + 2 --> f(x) + 2 shifts the graph 2 units up

In the graph of f(x)= log_3(x) , the x intercept at x=1

From the graph attached in the question, the x intercept at x=-1

Its means the parent graph is shifted 2 units to the left.

Option B: f(x + 2) --> x + 2 shifts the graph 2 units to the left
